I guess dating Ashton Kutcher makes you pretty popular, because Mila Kunis was swarmed by photographers when she left the gym in Beverly Hills yesterday!

Despite denying any romantic involvement with her former That 70s Show co-star, the lovebirds have gone out for romantic dinner dates, taken a trip and had several sleepovers since we first reported that they were an item less than two weeks ago.

And get this -- People has uncovered an interview from 1998 where Mila reveals that Ashton was her first kiss onscreen ... and in real life! Mila, who was just 14 at the time, told the mag, "I was like, 'Oh, he's so cute, it's the Calvin Klein model!' Then I was like, 'I have to kiss him?' I was so nervous and uncomfortable. I had the biggest crush on him. Ashton was so nice. He just made jokes and gave me funny little compliments. He made me laugh."

So what did Kutcher have to say about it? In 2001 he told the mag, "I'm the first guy she kissed? Oh my God, I had no idea! I'm so glad I didn't know that or it would've been too much pressure. I was so nervous. She acted so cool. She seemed as if she'd done it a thousand times. I was the one with butterflies in my stomach. I mean, here's this little girl and I have to kiss her. It was nerve-racking."

Hmm, so is she going to stick by her story that their relationship is strictly platonic?
